Antenna Standards
AMTA is currently working with the IEEE Antennas and Propagation Society (AP-S) to develop a standard on near-field measurements. [This is not the first time AMTA has worked with AP-S. Several years ago we worked with them on a RCS measurement standards.] The Near-Field Working Group consists of approximately 25 persons. All of the members of the working group are AMTA members and most are also IEEE members. We have been working for several years on the near-field standard. A draft is expected to be ready for the working group to vote on at its next meeting, which will occur during this fall’s AMTA Symposium. Many of the members of the working group have contributed by writing sections of the document, which is currently about 100 pages. If the working group approves the document, it will be forwarded first to the Antenna Standards Committee and then the IEEE Standards Association for their approval. If you are interested, the Near-Field Working Group will meet Tuesday October 12 (during the fall AMTA Symposium) from 5 – 6 pm in TBD room at the Westin Peachtree Hotel.

Technical Coordinator's Report
Many thanks to the authors who have submitted their papers and to the technical committee volunteers for all their efforts to date helping me assemble a very good technical program. That said, we have approximately 85 papers that have been successfully released and submitted, even though the number of abstracts was significantly higher (over 110). An apparent trend that authors will want to pay close attention to is the increasing amount of time required by many organizations to move through the public release process. In some cases, public release took from two weeks up to a month, and caused several papers to miss the publication deadline. A strong technical program is a critical component of AMTA, and a full set of quality publications is key to that. Please do not underestimate the need to complete papers at least one month before the deadline to allow for timely public release.
The featured technical paper included in this newsletter is from A. Capozzoli, C. Curcio, G. D'Elia, A. Liseno, P. Vinetti (Università di Napoli Federico II), M. Ameya, M. Hirose, S. Kurokawa, and K. Komiyama (National Metrology Institute of Japan [NMIJ]) entitled “Dielectric Probes, Compact Near-Field And Advanced Near-Field Far-Field Techniques.”
I often field comments from our membership regarding the understanding and use of the www.amta.org web site for which maintenance and upkeep has become increasingly difficult. You should know that your AMTA Board is committed to a professional web site and is planning for a new and improved site to be unveiled near the AMTA 2010 event timeline. Development will begin in August. More details to come in the next few weeks!
I am very much looking forward to seeing you in Atlanta in October!

Secretary's Report
Since the last newsletter, I received questions about how AMTA increases its membership. Recognizing that the antenna community is small (but special), the Board of Directors is active in promoting AMTA at various events through the year. As such, AMTA is present at EuCAP, regional events in the USA and other countries. Through sponsoring some of these events and being present at them, AMTA attracts individuals with an affinity to antenna measurements. We are also working with other conferences to include an optional AMTA membership in their registrations.
In return, AMTA provides a unique forum of experts in antenna measurements and specialized vendors where information is exchanged at the annual meeting and symposium. The papers database is an invaluable source of information that should be consulted before attempting to reinvent the wheel. In addition, our web site is being modernized to facilitate technical exchanges to supplement the annual conference. All this is happening now.
In addition to this, we are glad to have good hosts taking our annual meeting and symposium to beautiful locations!
See you in Atlanta!

Treasurer's Report
The fiscal year is rapidly coming to a close and I am happy to report that both AMTA and I are in a much happier place regarding our financial outlook. We have all been working very hard to keep expenses at a minimum (much thanks to my fellow board members who have endured my constant brow beatings).
In addition to maintaining tighter control over our spending, the annual membership fee was raised January 1st of this past year from $50 to $75. This increase was required to offset additional and rising expenditures AMTA has incurred during the past several years, and to supplement the reduction in symposium income that resulted from engaging conference management two years ago. Many thanks to John Rohrbaugh who managed to net $32K from last year’s symposium in Salt Lake City despite these challenges!
This past year, we also filed for a 501 ( c)(3) corporation status change with the IRS that would allow future symposium hosts to claim tax exemption in certain states. This change would also allow AMTA to accept deductible donations and award educational scholarships, both of which are currently not permitted under our current corporation status. We are awaiting the IRS ruling on this decision and hope to have more to report come October in Atlanta.
I am very excited about this year’s symposium program and am personally looking forward to seeing everyone there!

AMTA Senior Advisor's Report
Conference on Precision Electromagnetic Measurements
This year the Conference on Electromagnetic Measurements (CPEM) met in Daejeon, South Korea from June 14-18. This conference meets every two years, alternating between North America and other places in the world. The attendees come from many places in the world, especially from the national measurement institutes (NMIs). Examples of NMIs include the National Institute of Standards and Technology (NIST) in the US and the Korean Research Institute of Standards and Science (KRISS) in Korea. KRISS was this year’s host. The topics cover many aspects of electromagnetic measurements. Some examples include fundamental constants, atomic clocks, standards for the Smartgrid, RF measurements, and antenna measurements. One interesting bit of research that is going on are the efforts to relate the kilogram to Planck’s constant (the so-called electronic kilogram). The RF measurement sessions did not get underway until Wednesday.
This year, for the first time, AMTA had a special session (on Wednesday afternoon) at CPEM. There were five papers (20 minutes each for the presentation), plus two invited tutorials (of 50 minutes each). The program was as follows:
| Authors |
Paper Title |
Country |
| Vince Rodriquez |
Tutorial: Anechoic Chambers for EMC, APM, and RCS Measurements |
USA |
| Katherine MacReynolds, Michael Francis, and Douglas Tamura |
Comparison of Near-Field Methods at NIST |

| Jin-Seob Kang, No-won Kang, David Gentle, Katherine MacReynolds, and Michael Francis |
Intercomparison of W-Band Standard Gain Horn Antennas |
Korea |
| Michael Francis |
Tutorial: Estimating Measurement Uncertainties |
USA |
There were over 40 participants in the session. As you can see above, the papers came from several countries in the Pacific rim.
I cannot say enough about Korean hospitality. Dinner was arranged every night. On Sunday, the day before the conference, our host arranged an outing to one of Korea’s national parks (see Figs. 1 and 2). The park had some hiking trails and a Buddhist monastery. On Tuesday, arrangements were made to visit two organizations in Incheon that had EM measurement facilities. Among other things, we saw a tapered chamber, compact range and RFID test facility. Incheon is about two and a half hours from Daejeon. On our return to Daejeon, we visited a Korean folk village. This village was reconstructed to resemble a typical village of the 700s (see Fig. 3, courtesy of Jin-Seob Kang)
The conference concluded with a tour of the KRISS facilities and a barbecue hosted by KRISS.
Many thanks to our Korean hosts for make our stay a pleasant one!

The Return of Heirloom Produce
There was a time when cherished antiques were not the only things handed down through generations. So was the food on the table, until American agriculture began replacing its heirloom fruits and vegetables with hybrids built to handle machine harvesting shipping and shelf time at local supermarkets.
Heirlooms are making their way back in popularity. What’s the lure?
These specialty foods simply offer a rich diversity of nature’s best. Heirlooms are full of surprises—a tempting array of intricate textures, appetizing colors, exotic shapes, and exceptional flavors.
With such a reservoir of genetic diversity, heirlooms often have high nutritional values. For instance heirloom corn is a protein powerhouse with some containing 70 percent more protein than today’s hybrid corn.
Distinctive colors also contribute to many heirlooms’ nutritional richness. The pigments in red colored Chantenay or Punjabi carrots, for example, contain cancer – fighting phy-tochemicals such as lycopene.
What’s more, amino acids in heirlooms cucumbers, peas, and tomatoes often surpass hybrid varieties.
You are not likely to find heirloom produce at your local grocery store. But you can find these specialty all stars at farmers markets, roadside stands and specialty stores. Or try your hand at growing heirlooms in your backyard garden.
Heirlooms are experiencing a renaissance, and the reason simply boils down to a heritage of flavor. Discover for yourself how heirlooms may just be the “missing ingredient” in your recipes.
Examples of Tasty Heirlooms
Kentucky Wonder Pole Beans: Timeless favorite from 1864 with great old time flavor
Chioggia Beet: Tasty Italian variety introduced to American gardeners in the late 1840s, with alternating concentric rings in red and white.
Romanesco Broccoli: A masterpiece for both eye and palette, with spiraling apple green heads and a slightly sweet and nutty flavor.
Black Aztec Sweet Corn: This 1860s heirloom has white kernels in the milk stage that turn a soft, jet blue/black when dry.
Ping Tung Long Eggplant: Tasty and beautiful, with glowing dark lavender slender fruits up to 12 inches long.
Black Hungarian Pepper: Outstanding ornamental bears mildly hot peppers similar in size and shape to jalapenos, are black ripening to red.
Yellow Crookneck Summer Squash: Gives heavy yields of light yellow fruits and curved neck and slightly warty skin, has much more flavor than hybrid crooknecks.
Snows Fancy Pickling Cucumber: This 1905 introduction produces slender fruits that are great for fresh eating and salads.
All Blue Potato: Blue through and through, this midseason heirloom variety is packed with more minerals than standard supermarket hybrids.
Enjoy some of these heirlooms with your next cookout, it could be exciting!
